Wideband A/F gauge

Wideband A/F gauge
Finally had the O2 sensor bung welded in today.
......and yes, while they were at it I had them straighten out that right exhaust tip.
Very impressive Autometer gauge. I also connected a wide open throttle switch....no not for NO2 but it would work with that.......so the gauge will store the value for later recall.
Normally cruises at 14.5 and at WOT I see it hit 9.0
Still have that annoying part throttle stab 10 KR issue but it'* 0 at WOT. :?

9.0:1 Thats pretty rich ... I'm not a expert at tuning but I would think that would be alittle richer then what our cars like to make their best power at. What are you going to do for the part throttle KR?

Coming from a guy that saw 14.9 KR yesterday..that 10 degrees is going to pull back a load of timing long enough to affect power.
And is it me or has the number gone up again? This started as a low 2-3KR, progressed to 5KR, appeared in another thread as 7KR and is now 10KR? Yikes..
